My daughter (8) attends AWANA which is a kids club at our church.(Click here to learn more.) They have a Grand Prix, similar to the Scout's Pinewood Derby. Since I have a CNC router now, I thought I'd help her take her car up a notch. Between the use of Google SketchUp and Cut3D we were able to make an old Ford Cobra which was pretty close to scale with the real thing. I did have to squish it a bit in order to fit in the rules. She was very proud. (OK dad may have been a bit too involved this year. She did have lots of fun working together with me though.)
